Taken just after sunset on a chilly, breezy evening. I wasn't hopeful that I would get anything mainly because of the conditions but also because I only had a few minutes to shoot the scene.

This version was made by stitching two bracketed layers in Autopano then messing about with them in Photoshop. There is an alternative but smaller version made from the same two stitched gigapans here www.gigapan.org/gigapans/64038/
The light around the horizon interests me. Obviously it is brightest where the sun is but why the patches of brightness elsewhere? It shouldn't be vignetting because the 18-55 was set at 18mm. Actually, the tone-mapping in the other version has accentuated these artifacts so you can see the "structure" of the light better. I'd like to know what is going on here.

Woot! So in fact I should be pleased to have these
interesting formations in my image rather than
disappointed to have some sort of abberation in my
images. Plus I can rename theother pano and get to
use the word "Sundog" in the title. How
cool is that? :-)

Those are sundogs, Kilgore: en.wikipedia.org/wiki/Sundogs&nbsp
;Sundogs are
very apparent in winter up here in the Frozen
North, where there are lots of stratospheric ice
crystals to reflect the sun. I suspect your tone
mapping has brought out a phenomenon you
wouldn't have noticed with the naked eye.
